The classical SIR model is used to model the disease spread. It divides the population into three non-overlapping classes: susceptibles (S), infected, (I), and recovered (R). The model describes how the number of individuals under each of the classes changes over time. These changes are described according to the system of ordinary differential equations below:
\( \beta \) is the effective transmission rate while \( \gamma \) is the removal rate. The model assumes a closed population (i.e. constant population). This means that at each time \( t \), \( S + I + R = N \), where \( N \) is the total population. Read More.
